CAR-DOOR,

Application filed. July 28, 1917.: Serial No. 183,248.

Toall whom it may. concern: I w

Be itknownthat'I, Gnsmio SnRo, a subjectof the King of Italy, residingat Carneyville, in. the-county of'Sheridan andState of lvyoinin'g haveinvented certain new and usefullmpnovements in GanDoors; of which thefollowing, is a specification.

This invention relates to an'nnprovement in car doors, andpa'rticularlyto an auxiliary door adapted to be fitted for use upon box andi'otherlike carsto adapt thesame for ex peditious' handling and shipping. of'grain, coa1,',andthe.lilie. v

An object of' my invention is to provide a. structure which can be builtintoa' car when the same is constructed in the shop, or which can befitted to cars already in use the structure being such'tha-t it -.is notnec 'essary to remove the usual sliding door or to "otherwisegreatlyalter or reconstructthe standard construction of cars.

A further object lies in constructing parts in such a way "that when thecar is to-be unloaded, the door structure can be folded and swung,outfro n the, doorway of the car and can be movedaround' torest'against' the outerside of the sliding door thus being 7 thatloading'oir unloading of the cars will not be interfered with,' and"which" structure has the parts thereof so hingedtogether that they canbe folded to be swung inside ofi'the carand to begreceived'entirelywithinja pocket orrecess provided .on the leaving ou'tya section ofthelining as ordinarily employed5,. in which position of the parts thedoor will not ofier any material protrusion from the wall lines of thecar.

' A still further object resides inproviding means by which the severalsections of the door are braced one; against the other and by whichthedoor structure willibeybraced and held as substantially a continuousstructure,

when in use; together withbracing structure adapted for attachment tothe door structure and'for engagement with the car frame to thus rigidlymount the door against" displacement, from the: door opening and topresent substantiallya continuation of the car side. 7

With the above and other objects in view,

which will be inpa'rt' described andin part from the' specification,-drawmvention consists in understood.

certain" novel features of construction and:

combinations of parts which will be hereinafter-more-'fu1lysct forth.

Fig. G'isa horlzon-tal sectional. view. taken on the line 6-6 of Fig. 4;and Fi 7 is a horizontal sectionalview on the line 3 of Figpflgandlooking in vthe di- -r'ectionindicated by the arrow.

As has been stated; thevdoor structure,

constructed after the manner of my muchtion, can-be fitted foruseinconjunction with 'box cars, or cars 'of' other types, and inthepresent instance whereI have shown the door as appliedto. 2LbOX car, theparts are for the most part;

v substantially without change from standard construction.

llhe side wailil of the car has the dooropening 2 provided therethrough,and: a sliding-door 3 operating on a track 4, is providedto close theopening 2. Toiall intents and purposes, the car construction issubstantially standard; with the exception. that. at one side of thedoor opening 2,:theinner lining or wall 5 'jas now ordinarily usedinxcar construcinto a recess in the wall metal,comprises the rathernarrow-sections or slats 7 8, and;9, which arefoldablycconnecte'dtogetherby means of hinges asxindicated at 10 and'll,and a relatively wider section or panel 12, which ismounted uponthe-outeredgeofthe sectionz9, by means of::

usz-foldably connected to be 'swung'back againstthe slats "7 ,8; and 9.Hinges 14' are connected with Y the door secti'on 7 and then by use ofbolts 15, or other suitable fastenings, the entire door structure ismounted in place upon the car structure to swing upon the hinges 14. Thehinges 14 mountthe door structure at one side of the recess or pocket 6on the inner side of the car wall, and the Width of this recess orpocket is sufiiciently great that when the door section 12 is swung backagainst the sections 7, 8, and 9, and the entire structure is moved in aswinging path upon hinges 14:, the folded door structure as an entiretywill be received in thispocket or recess 6, in which relation the partsare held against return movement by means of a spring latch 16 which iscarried by the car structure. Through the fact that the hinges 10 and 11by which the sections 7, 8, and 9, are connected together are disposedto be on the outside when the parts are swung into the recess, andthatthese hinges are of the single acting type, or are adapted to swingin only one direction, this spring latch 16 will hold the doorstructureagainst dis placement from the recess and closing or extension ofrany ofthe parts therefrom will not be permitted, thus making the doorstructure conform substantially to the lines of the inner Walls, andgiving to all intents and purposes a substantially continuous andunbroken car wall. I

The construction of the inner portion of door to comprisethe sections 7,8, and 9 permits the structure to be swung out, through the fact thattheslats will fold around the door post, while the main panel of thedoorwill be swung to be entirely outside of the car and to restand'bearagainst the outer side of the sliding door 3, this setting ofthe parts being shown in Figs. 2 and 7 Toprovide for securing the doorstructure in this fullopened relation, hooks 17 are carried by the freeend of the panel 12 and eyes 18 are provided on the door 3, to which thehooks Y may be fitted.

From the foregoing it will be seen that the door sections are more or,less flexibly connected together and as considerable weight is placedupon the 'door structure when the car has grain, coal, or othercommodities loaded thereinto, it is natural that the car door will beforced and bulged out when it is brought to the closed position, un-

less braced and rigidly held in place. With this purpose: in' view, Iprovide an inside brace member 19, which isfadapted to be placedacro'ssthe hinge joint, between sections 9 and 12 of the doorand to berigidly secured in place thereon by: the use of bolts 20, it of coursebeing understood that in view of the factthat the'hinges 10 and lllareplaced on the outer sides of the sections 7, 8, and 9, as theseparts are set in clos ing the door, bulging of these sections outwardlyis not permitted. The mounting of inside brace bar 19 will act to verymaterially stiffen and hold. the door sections, and while the hinges 10and 11 will restrain the sections'7, 8, and 9, against bulging, it ispreferable that additional bracing be introduced to reinforce thestiffening accomplished by brace 19, and also that bracing be providedto relieve the strain upon the hinges- 10 and 11, and this can beaccomplished by bars placed on the outer side of the door. With thesepurposes in view, I provide openings 21 and 22 in the inner side edgeand the sill respectively of the door framing, and provide a relativelywide bar or plate 23 which has a brace bar 24, pivoted thereon bymeansof pin 25. This plate 23 has bolt receiving openings through the upperend thereof and the bolts 20, by which the inside brace bar 19 ismounted in place, or other suitable bolts are used in rigidly mountingthis plate 23 upon the door sections, it being preferable that fasteningbe accomplished to secure the bar or plate23 to the section 9 and alsoto the section 12.

This will maintain the outside bracing members. in a rigidly mountedposition in the keeper slots or openings 22 and 21 rethe hooks 17 areinserted in eyes 26 carried by thatdoor post opposite to the one onwhich the hinges lt are mounted, and in this Way the door structure asan entirety is braced and reinforced in its body'portion and is rigidlysecured to the door posts at opposite sides of the door openings. 7 c

When the door is closed and secured as above set'forth it will of coursebe understood that to open the same it will be necessary to remove thehooks 17 and the eyes 26, and to remove the bolts 20 so that the insidebrace bar 19 and the outside plate 23 having the bar 24.- carriedthereby, can be removed and when this has been done thesections haveunrestrained swinging movements. If desired, pins or studs 27 and 28 canbe provided on the inner sides of the slats 7 and 8, to have the insidebrace member 19 and the outside plate 23 hung thereon, to retain theseparts against loss when the door is not in use.

As the manner of mounting and of using the door'has been rather fullydescribed as the description has progressed, it is not here believednecessary to go further into the manner of use. However, attention mightbe called to the fact that when desired the the sliding door 3 andobtaining access to the bolts by which the door structure as an entiretyis mounted in conjunction with the car structure.

lVhile I have herein shown and described the various parts as beingconstructed in certain specified ways and as being connected in aprescribed manner, it will be appreciated that variations might be madein the materials used, in the manner of constructing the parts, themanner of mounting the same for use, and in other structural andassembly features, and hence I wish to be limited only to such points asmay be set V forth in the claims.

I claim:

1. In a car door structure, the combination with the car wall having adoor opening with posts at opposite sides thereof, and a recess adjacentone post, there being an opening in said post and an opening in thesill; of a door made in sections hingedly connected with each other andhinged to said post so as to fold into said recess or to unfold andextend across the door opening, a plate removably seated in the openingin the sill and rising alongside the door when distended, means forremovably securing it to said door, and a brace bar connected with theplate at one end and with its other end seated in the opening in saidpost.

2. In a car door structure, the combination with the car wall having adoor opening with posts at opposite sides thereof, and a recess adjacentone post, there being an Copies of this patent may be obtained for ingin .the post and connected at its other end with the first-namedelement, and bolts passing through this brace structure and certain ofsaid door sections, for the purpose set forth. Y

3. In a car door, the combination with a wall structure having spacedposts at opposite sides of a door opening and a recess in the sill ofthe latter; of a door made in sections hingedly connected with eachother and one endmost section hingedly connected with one post, anupright brace element mounted at its lower end in said recess andstanding outside the door across the hinge line between two of itssections, a horizontal brace element standing inside the door andcrossing a plurality of hinge lines, and bolts removably passing throughboth elements and the interposed sections, for the purpose set forth, a
